Ajax Error

[Frederick]

I have two gateways that calls my app for callback reasons. One of them expects a "200" response and the other needs the "OK" response. In UniServerModule's OnHttpCommand event, I added the following code:-

    AResponseInfo.ContentText:='OK';
    AResponseInfo.ContentType := 'text/plain';
    AResponseInfo.ResponseNo:=200;

When I run the application, I get an "Ajax Error: OK is not defined" all the time.

What am I missing here and is my above code correct in returning the responses to the gateways?

Hello,

Handled := True;

?

I can't use "Handled:=True" because the app just returns "OK" and stops.

I want the app to respond to the calling gateways and then proceed to the login screen.

Sorry, I don't understand your case. Please explain in more detail...

My app has one login form. Normally, when I call the app from the browser, the login form appears.

If I put the following code in UniServerModule's OnHttpCommand event, the browser displays an "OK" and then stops. The login form does not show.

    AResponseInfo.ContentText:='OK';
    AResponseInfo.ContentType := 'text/plain';
    AResponseInfo.ResponseNo:=200;
    Handled:=True;

How do get my app to return the response code of "OK" to my browser AND show the login form?

@Frederickhello, try this:

UniServerModule's OnHttpCommand

var
oldContent : String;
begin
inherited;
    oldContent := AResponseInfo.ContentText;
    AResponseInfo.ContentText := 'OK';
    AResponseInfo.ContentType := 'text/plain';
    AResponseInfo.ResponseNo := 200;
    Handled := True;

    sleep (2000);//add a 2 second delay to get the first response (but may not be necessary)

    AResponseInfo.ContentText := oldContent;
    Handled := False;

end;

 

you can try this in UniGUIServerModuleHTTPDocument too.

Thanks for the code. This seems to work.

What advantage is there in using this code in UniGUIServerModuleHTTPDocument compared with in UniGUIServerModuleHTTPCommand?

nothing important, you can just try to return OK (200) when the document is filled not on every request.

Noted. Thanks.
